One is to put the equipment in the cabinet. Some people put the equipment into the customized cabinet for decoration and protection. This will cause the sound to be turbid due to the latent vibration caused by the space inside the cabinet. The equipment such as power amplifiers are not easy to overheat and age due to insufficient circulating air. If you put the speaker into the wall, the sound will become hard.
The second is to stack equipment. Many people like to put the players such as DVD players, amplifiers, tuners, and digital-to-analog converters on top of each other, which will cause mutual interference. Especially, the radium camera and the power amplifier have serious interference, which will make the tone hard and suppressive. The correct approach is to place the equipment on an audio frame designed by the factory.
Third, the power plug is positive or negative. The good system of positive and negative power plug processing, the tone color is clear and natural, smooth; positive and negative inconsistency or uneven, the tone will be hard and rough.
Fourth, the wiring is not strong and unclean. If the system sounds dry and hard, one of the reasons may be poor contact, such as poor plug, oxidation of the contact surface, dust or oil stains, etc., so check frequently to keep the contact surface clean.
The fifth is to use marble or glass to carry equipment. The low density of the marble and the high resonance will affect the sound effect. The density of glass is higher than that of marble, but it is not thick and the resonance is more serious. Granite or granite, especially masonry, can be used with the highest density and ideal carrying equipment, but the thickness is more than 3 cm.
Sixth, the placement of the speakers is "adapted to local conditions." Some people have other furniture in the room, and the speaker is placed in the position of the furniture. The correct distance should be determined first, then the speaker should be placed 1/3 of the distance between the seat and the opposite wall. The distance between the speakers is 0.7 times the distance between the listener and the speaker. The height is equal to the listener's ear and the tweeter. .
Seventh, the wiring is not handled properly. Do not tie the power cable to the signal cable when handling the wiring, because the AC power will affect the signal; the signal cable or the speaker cable can not be tied, otherwise it will affect the tone; the signal cable or speaker cable can be shortened if it is too long. Many signal lines are directional, don't make a mistake.
Eight is to take care of the room sound effects. In addition to sound, sound insulation, more important is the processing of sound reflection, refraction, which needs to consider the size, size, firmness, use of materials, etc. If you are not a connoisseur, even if the decoration of the room is luxurious and beautiful, the sound is difficult to achieve. best effect.
Nine is blindly imitating. Do not start from reality, blindly imitate others. For example, people have long-term signal lines and short speaker cables. This is because the front and rear stages are balanced with the laser, and your equipment is not balanced. It is difficult to achieve the same effect.
Ten is self-deception. If the equipment plays a certain kind of concert, the effect is very good, but playing another type of music is not ideal. This means that the system has not reached the ideal level, and it needs to learn more, listen more, observe more, and improve it.
Whether the game can be played smoothly depends on the low latency of the projector, whether it can be optimized to within 30ms, or within 50ms, which is difficult for non-professionals to perceive. However, the cable and network speed and the configuration of the computer (game console) have an impact on the game delay, so you can't completely throw the pot to the display device.
The first is the problem of memory. Be sure to choose a larger one, the bigger the better, otherwise the screen will freeze. The second is that the resolution must be above 1080p, otherwise the details of the projected game screen will not be clear, which will greatly affect the game experience and viewing experience. The other is about motion compensation. The game screen is generally faster for animation playback. It must be equipped with motion compensation, otherwise the screen will be stuck.
